The young man pictured here was seated outdoors, as he was in the process of completing an exercise session. At this point in his routine, he was performing a weight training exercise known as a biceps curl, which is intended to build the participant’s biceps muscle, as well as the forearm flexors. The weight, in this case a 30Lb dumbbell, is grasped by a closed fist, palm up, and when flexed, the arm lifts the weight up to the shoulder.
